To (ti/Z whom it may concern:

Be it known that 1, CHARLES STUMMA, a citizen of the United States, residing at Bran vdon, in the county of Buchanan. and State of Iowa, have invented a new and useful Motor-- Vehicle, of which the following is a specification.

This invention relates to motor-vehicles; and it has particular reference to the driving and the running-gears of. this class-of vehicles, the objects being to simplify andimprove the construction and operation of the same, to facilitate the steering or turning of the machine, and to produce a machine of this class which shall possess superior advantages in point of simplicity, durability, and general efliciency.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved constructipn and novel arwill be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawin s has been illustrated a simple and preferred form of the invention, it being however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but

that changes, alterations, and modifications the scope of the invention may be resorted to when desired.

In said drawings, Figure 1 is a top plan view showing the frame and driving-gearing of a motor-vehicle embodying the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail front view. Fi 4 is a sectional detail view taken on the p ane indicated by the line a i in Fig. 1.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The traction-wl1eels 1 1 of the improved vehicle are mounted for rotation upon the spindles of an aXle 2, extending transversely under the frame 3, which latter has been shown of rectangular shape and provided with cross-pieces 4 and 5 and with a longitudinal brace 6, connecting the front crossbar 5 with the front member of the frame.

Securely connected with the traction-. wheels or with the hubs of-said wheels are spur-gears 7 which are driven by pinions 8, mounted upon the outer ends of short shafts 9, which are journaled in :10 upon the side members of the frame, said shafts being provided at their inner ends with bevel-gears 11, which are ada ted to be driven by bevelpinions l2 12 an 13 13, saidbevel-pinions being feathered or splined upon shafts 14, as by means of splines i5. Theshafts 14, which are journaled in bearings upon the cross-bars i and 5, are provided at their front ends with bevel-gears l6 and 16*; meshing with and driven by bevel gear-pinions 17 and 17%.

which. are keyed upon shafts 18 and 18 which are gournaled in axial ahnementwith each other in boxes or bearings upon the side members of the frame and. upon the longitudinal brace member 6, the inner ends of said shafts abutting upon each other, as indicated by dotted lines in Fi 1 of the drawings.

The other ends of the shafts i8 and 18 carry spurcars 19, which are formed integrally with and-wheels 20, said combined spur and band'wheels being supported loosely upon the respective shafts. Said shafts are provided with cone wheels or pulleys 21, splined thereon and rotatabletherewith, said conewheels having hubs" provided with annular grooves 22, enga ed by the forwardly-ere tending bifurcate arms 23 of bell-crank le vers B, fulcrumed upon the frame, the laterally-extending arms 24 of said levers being connected with suitable operating-rods 25,.

whereby they'may be conveniently manipu lated to move the cone-pulleys upon their respective shafts.

The combined spur and band wheels are provided u on the rims thereof with friotionaces 26, a a ted to-be engaged by shoes 27, which are ra ially'slidable upon the spokes or bodies of the wheels and which are provided at their inner ends with concave members 28, assembled around the cone-pulleys and adapted to be actuated by the latter. Eachof the combined spur and band-wheels is equipped wi Lh a lurality ofsa fourfriction-shoes and reated parts, inc uding the concave members or segments 28, which latter maybe engaged by the cone-pulleys to force the friction-shoes into active engagement with the friction-rims of the combined spur and band wheels.

A transverse shaft 29 supported in bearings upon the side members of the frame, is provided at the ends thereof with inions 30, meshingwith the spur-wheels 1 9. he shaft 29 has been shown asequ-ippedwith a sprocket wheel 3 1 ada tedto receive motion by means of a belt oiri thelsourceof powenwhich Qil consists of.

'"o'tor supported u. on the frame of the machijn but wl'iich me not been show u in the drawings.

Upon the front end of the frame is mounted a heavy clip 32, which is secured in part upon the longitudinal hrace 6 and through which a heavy bolt 33 extends into the front member of the frame. Pivot ally mounted upon said bolt is a tiltingbeam 34:, between which and the frontineiuher of the frame there are interposed washers and wear-plates 36. Through the ends of the beam. extend vertical bolts 37, upon which are mounted for 1'0- tation sleeves 38, connected with frames 39, in which the frontcztster-whoels 40 are supported for rotation. t will. be readily seen that said castenwlneels will yield to the direction to which the vehicle steered and that the tilting beam upon which said casterwhcels are supported will readily adapt itself.

to rough and uneven ground.

Suitably supported. upon the side members of the frame are pairs of levers 41 and 42, said. levers having bifurcated. ends engaging annular groovesdfi and 44 in the hubs of the hevei-pinions l2 and 13, respectively. The outer ends of the shipping-levers 41 and 42 are coi'iuected in pairs by means of operatingrods a; oer 4 ey maybe readily manipulated to shift the relative positions of the hevrilqiinitins 52 and 13.

in operation motion is. transmitted from the source of power to the shaft 29, which transmits to the combined spur andihand whiiiels it and 20, ither or both of which may be utilize i. when the vehicle is stationary for the purpose of driving machinery of any kind. By i'i'ianig'iuiating the rods 25 to move the cone-pulleys 21 in an outward direction the frieti. mshocs will be thrown into engagement with the frictirm-rims of the comhinod spur and hand wheels, which latter, being thus connected with the shafts l8 and 18*, will rotate the latter, transmitting motion to the longitudinslly-disposcd shaft 14. By mimipulating; the operatii'ig rods 45 to properly adjust the bCVOr-PllllOilS l2 and 13 moti on may he trai'ismitted to the traction- Jheels to rotate the latter simultaneously in a forward or rearward direction, according to the direction in which it is desired to drive the vehicle, or the hevel-pinions may be adjusted to} drive one of the traction-wheels in a for and the other in a rearward direction, is causing the frame of the vehicle to be turi'ied or rotated in a horizontal plane. The vehicle may thus he very q uickly and of liciently steered by mai'iipulating one of the Opfirithll]P'--1O(.ifi The steering may also be effected by temporarily suspending; the operation of the soaring on one side of the vehicle Toy manipulating one of the opera ting-rods 525.

it is obvious that means, such as handlcv-us, may be pro dried for the purpose of manipufaring he opiwy' tinguods 15:; and 4-3 and that other means, such as ordinary quadrants, may be provided for the purpose of re taming such levers at various adjustments. These devices, however, are well known in the art and have not been illustrated. in the drawin s.

It will be evident from the foregoing dc-- scription that in this improved machine the motor may be run continually in one direc tion, and that the power may be utilized without stopping or reversing the operation of the motor to propel the vehicle forwardly or rearwardly, as may be desired, or to turn the vehicle while in motion, andthat at the same time the vehicle may be stopped at any place and the power be utilized for the purpose of driving stationary machinery. in the latter event the bevel-pinions 12 and 13 will be adjusted at an intermediate position where neither of said pinions will be in engagement with the bevel-gears 11. When stationary machinery is thus driven, one side of the gearing may be permitted to remain idle, as will be readily understood.

Having thus described the invention, what is claimed is- 1. In a motor-vehicle, traction-wheels having spur-gears connected therewith, shafts having pinions meshing with said spur-gears and provided at their inner ends with bevel gears, and means for driving the latter ineluding shafts supported independently for rotation, pairs of inions slidable upon and rotatable with sai shafts, and means for effecting simultaneous adjustment of the pair of pinions upon. each of said shafts independently of those upon the other shaft.

2. In a motor-vehicle, a pair o independent alined shafts, a driven shaft parallel. thereto and having pinions at the ends thereof, spur-gears upon the independent shafts meshing with said pinions, friction means for connecting the spur-gears with the shafts upon which they are loosely mounted, a pair of traction-wheels, and means for transmitting motion from the independent shafts to the respective traction-Wheels.
